FLUSHING APPARAT'US.

Speciflcation of Letters Patent.

Application filed August 24, 1907.

Patentcd May 3, 1910.

Serial No. :389,934.

To all whom tt may concem:

Be it known that I, PAUL S. MILLICE, a citizen of the United States,residing at Hamilton, in the county of Butler and State of Ohio, haveinvented certain new and useful Improvements in Flushing Apparatus, ofwhich the following is a speeification.

My invention relates primarily to that character of flushing apparatusintended for use in connection with water closets, and has for itsobject the providing of flushing means whereby the fiushing may beaccomplished by direct flow from the water service, such as a city orother public service, under the direct pressure of said service.

My present invention is an improvement on the flushing apparatus showndescribed and claimed in my application tor Letters Patent of the UnitedStates, filed August 3, 1906, Serial No. 329056.

The invention will be further readily understood from the followingdescription and claims, and from the drawings, in which latter:

Figure 1 is a side elevation of my improved deviee shown connected upand aplied to a water closet bowl. Fig. 2 is a ront elevation of myimproved device. Fig. 3 is a rear elevation of the same with theOperating hanclle partly broken away. Fig. 4 is a central verticallongitudinal section of my improved device,.shown on the line w-x ofFig. 2, partly broken away. Fig. 5 is a plan vew of my improved deviceand, Fig. 6 is a bottom view of the same.

1 represents a closet. bowl, with which my improved device is adapted tobe connected by a suitable coupling 2.

3 represents a casing in which there is a fluid passage 4 with which achamber 5 has connection through a port 6, the chamber havingcommunication with the water service, as by means of a supply pipe 7,the pipe being threaded into an opening 8 of sub stantially greaterdiameter than the port 6. This permits a supply pipe having a bore 9 ofgreater cross-section than the port 6 to be employed for the purpose ofproviding an infiow through the opening 8 of greater Volume than thecapacity of the port 6 for forming a back pressure in the supply-chamber5 the port 6 forming the discharge opena pressure-compartment 10 fromwhich a port 11 communicates with the fluid passage there being howcver,a web 12 in the fluid passage for forming a cavity 13, whose mouth 14opens into the fluid passage in the direction of flow of water throughthe fluid passage, as indicated by the arrow a. The web 12, cavity 13and mouth 14 are preferably located within the longitudinal projectionsof the walls of said fluid-passage at the discharge-end of the same. Atthe port 11 there is a valve seat 15 for accommodating a valve 16 on avalve stern 17 operated in suitable manner, as by means of the lever 18having the pivot 19 on the lug 20, and having a screw 21 pass through aslot 22 in the upper end of the stern.

24 is a compression hearing for the valve stern. This hearing isthreaded into a thrcaded opening 25 in the casing of larger diameterthan the valve-seat 15. A spring 26 is interposed between the hearingand a collar 27 on the valve stem for normally causing seating of thevalve 16.

31 is a valve-shell Secured in a threaded opening 32 in the wall 33 ofthe casing, which wall separates the pressure-Compartnent from the fluidpassage. The shell accomnodates a compound valve 34 which is preferablya triple valve, comprsing the valves 35 36 37. The compound valve has astern 38 adapted to reciprocate in the bearing 39 in the shell. Thevalves 35 36 37 are respectively adapted to seat against the valve seats40 41 42, respectively at the port 6, at the hearing 39 and at thelarger end of said shell. The valve 37 preferably takes the form of aflap-valve or thin disk of flexible rubber or leather or other suitablesubstances Secured to the outer end of the hub 43 of the compound valveby means of a Washer 44 and screw 45. The valves 35 36 are preferablycompression valves in the form of disks of rubber, leather or the like.They are held in place by providing the valve-stern with a reduced end46 about which the disks 35 and 36 are received at the respective sidesof a collar 47, a Washer 48 and screw 49 securing the parts in place.The body of the shell serves as a bearing for the hub 43 of the compoundvalve. This hub is of greater diameter than the port 6, that is ing orsaid chamber. The casing also has i to say, the opening of the valveseat 42 is a threaded cap 51. There is a passage 55 in said casngbetween the chamber 5 and the pressure-compartment, forming a bypassaround the compound valve. 56 is a plug threaded into said passage andheld in place by a lock-nut 57 the said plug having a head 58 forturning the same., This plug has a valve seat 59 theren adapted to beengaged by a valve 60, shown as a needle valve on a threaded stem 6lthreaded into the plug 56, a lock-nut 62 serving to lock the stern inplace in the plug. These lock-nuts 57 62 also serve to prevent leakage.The plug is provided with a port 63 which communicates with the bore 64of the plug so that the fluid may pass from the chamber 5 through theport 63, bore 64, valve seat 59, and by-pass 55 into thepressure-compartment.

It will be noted that the diameter of the opening in the valve seat 59is of substantially less cross-section than the port 6, the supplyopening into chamber 5 in turn being preferably greater than said port6. If now the valve 16 be raised, the pressure in thepressure-compartnent is relieved and the fluid in thepressure-compartnent will be received by the fluid passage. As soon asthe pressure in the pressure-compartment is relieved, the compound valve34: will unseat from the seat tofor permitting flow through the port 6.The pressure from this port will force the compound valve away from saidport for causing the valve 36 to seat against the-valve seat 51 forpreventing leakage around the compound valve from the fluid passage intothe pressure compartment, the valve 16 having meanwhile been closed, andcompelling the filling of the pressure-compartment to be accomplshedthrough the bypass, so that the moment of shutting ofl ot the flushingmay be definitely determined. The 'supply water takes the course of thearrow a into the bowl, the web 12 protecting the flow from thepressure-compartment through the port ll for preventing shutting ofl' ofthat flow while the valve 16 is open. The supply opening being greaterthan the port 6 will cause part of the fluid to pass through the valveseat 59 and by-pass 55 into' the pressure-compartment. This opening inthe valve seat 59 is comparatively small so that greater pressure willresult in the pressure compartrnent, which will be eXerted upon the topof the compound valve for causing the valves 35 37 to be seated when thepressure in said pressure-Compartment has overcome the pressure of theflow through the port G against the bottom of said valve, this seatingbeing accomplshed with comparative rapidity.

My improved device is simple 'in Construction and practically noiselessin operation.

Having thus fully described my invention what I claim as new and desireto secure by i Letters Patent is:
